' CONVERTIBLE MONKEY AND PIPE WRENCH.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed June '7, 1906. Serial No. 320,550.

To ail whont it WI/CZ/y concern:

Be it known that I, JOHN T. LANDERS, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Convertible Monkey andPipe \Vrenches, of which the following is a specification.

My invention relates to improvements in a combination monkey and pipewrench, whereby the former is converted readily and easily into thelatter; and the object is to overcome the necessity of having to laborunder the inconvenience of using two separate wrenches for two differentpurposes where one would answer for both purposes as intended, therebyeconomizing time and labor, thus avoiding the inconvenience of lookingafter separate wrenches for doing the work one would answer for.

To this end the invention consists in the construction and combinationof parts, as will be hereinafter more in detail described andspecifically claimed.

I have fully and clearly illustrated my invention in the accompanyingdrawings, in which Figure 1 is a longitudinal side elevation of amonkey-wrench having my improved attachment applied thereto. Figs. 2 and3 are detached views of said improved attachment.

Referring by letter to the annexed drawings, in which like lettersindicate corresponding )arts, A designates a wrench of the monkey-typeconstruction, which of course in itself forms no part of my invention,but only so far as when used in combination therewith of the attachment.

B and B designate the usual twin grippingjaws, the former, B, beingrigidly secured to one and the forward end of a shank C, and the latteror opposite jaw B having an opening or slot therethrough by which it isslidably secured upon said shank, this sliding jaw B having a slottedextension or lug D, through which the shank C is also passed. Thisextension or lug D of the movable jaw B is provided with a socket d inits lower or rear portion, in which an adjustingscrew D, having athumb-nut E secured thereon at its rear end, takes, through the mediumof which the movable jaw is adjusted relatively to or from thestationary jaw.

F designates a detachable pipe-wrench attachment or jaw of peculiarconstruction and to which great importance is attached. This jaw isformed of one piece of metal and is vertically bifurcated into twointegral gripping parts formed parallel with each other. The upperportion of this jaw for about midway its length is of rectangular form,the point of indication being shown at f in Figs. 2 and 3. From thenceto the lower portion thereof it is angular and terminates inaright-angular lip or flange, as at and), upon the forward edges of saidjaw and fits snugly up to and beneath the lower end of the stationaryjaw B, as clearly shown in Fig. 1 of the drawings. Upon the rear edgesor angular portions of the jaw F are formed teeth G, which serve asgripping-surfaces by which a pipe is firmly held in position when thewrench is in use.

H designates a set-screw which engages a socket h, formed centrally inthe upper portion of the jaw F, by means of which tension is given tothe jaw, as occasion requires.

From the foregoing description, taken in connection with theaccompanying drawings, the operation of my device will be obvious, butmay be briefly rehearsed as follows: In the operation of my device whenthe operator desires simply a monkey-wrench my attachment or pipe-j awis detached from the shank of the monkey-wrench by unscrewing theset-screw located in the rear and upper portion of the pipe-jaw, and theimplement from which it is detached becomes a monkeywrench, and if apipe-wrench is desired it can be readily converted into the same byslipping the said pipe-j aw over the shank of the monkey-wrench andbetween the stationary and movable jaws of the same and then tighteningup the set-screw. The implement will then become a pipe-wrench oralternately a monkey and pipe wrench, thus serving a twofold purpose,thus overcoming the trouble and inconvenience that two separate wrencheswould occasion, and other numerous advantages are also derived from awrench of this character. This wrench attachment will [it all sizes ofmonkey-wrenches and can be applied instantly and can be used to eitherjaw of wrench. wrench can be converted into a pi e-wrench, also be usedindependently of t e attach- The monkeyment. This attachment will workon a in the rear of the supplemental jaw for the 10 smaller pipe thanothers, also work on as adjustment thereof.
